What It Is

This is a carburetor fuel filter gasket replacement kit for Kohler Command engines (CV18S, CV20S, CV22S, CV725). It replaces the seal between the carburetor body and the fuel filter bowl, preventing air leaks and fuel seepage that cause rough idling or stalling.

Fitment & Compatibility

• Direct fit for Kohler Command CV18S, CV20S, CV22S, and CV725 engines (horizontal or vertical shaft).
• OEM cross-reference: 24 853 25-S, 24 853 19-S, 24 053 08-S, 24 053 50-S, 24 853 50-S.
• Check your engine model number – not just the series. Look on the engine shroud or valve cover for a full model/spec number (e.g., CV20S-12345). This kit does not fit Courage, Pro, or other Kohler series.
• Measure the bowl gasket diameter – it should match the carburetor bowl’s outer lip (approx. 2.5 inches). If your bowl is smaller or larger, this won’t seal.
• Aftermarket replacement; quality is comparable to OEM, but inspect the rubber gasket for flash or mold lines before installing.

Key Things to Know

• Installation difficulty: Easy (30-minute job) – just a screwdriver and maybe a small pick to remove old gasket fragments. No carb removal required on most engines.
• Common gotcha: Old gasket often cracks and sticks to the bowl. Scrape it clean – any leftover debris will cause a leak.
• Fuel line check: While you’re in there, inspect the fuel line for cracks. A leaking filter gasket can mask a split hose.
• Torque lightly: Over-tightening the bowl nut can warp the gasket or crack the bowl. Hand-tighten plus a quarter turn is enough.

Should You Buy It

If your Kohler Command engine has a fuel filter bowl that weeps, drips, or causes hard starts, this kit is a cheap, fast fix. It’s ideal for DIYers who want to avoid a $150 carburetor replacement. Skip it if your engine model isn’t listed or if the bowl itself is damaged.
